  1. Geography of String Vacua with Minimal (N=1) Supersymmetry Sergei Gukov Type II on CY 3-fold with fluxes/branes M-theory on G2 manifold F-theory on CY 4-fold Heterotic on CY 3-fold the `right’ vacuum

  2. Why N=1 String Vacua? • Building realistic models of supersymmetric particle physics and gravity • New tools in superstring phenomenology (e.g. flux compactifications) • New string vacua, new dualities, new semi-classical limits which are not seen by the perturbative string/field theory • Non-perturbative dynamics of gauge theories (e.g. important properties of strongly coupled gauge theories, such as confinement and mass gap may be given a simple explanation in M-theory on G2 manifolds) • Related developments in mathematics • If we are lucky, we may see some of this physics at LHC!

  3. Topological String Partition Function: [BCOV,Witten] Ztop= Wave Function Entropic Principle: Which String Vacua are Preferred? String Cosmology: a Toy Model asymptotically free theories are preferred! based on recent work with K.Saraikin and C.Vafa
